So, I have a cammed 5.3 with a flowmaster 40 dumped before the axle. It's stupid. I drive this everyday, and while it was cool at first. It's really annoying now. I want something REALLY quiet. Maybe even like 2 REALLY LONG magnaflows and just run a cut-out before those. I want it to be as quiet as possible... until I want to race

 

flopro hd mufflers.

 

corsa

 

Stock muffler with a cut-out HA HA!!

 

i got the exact setup youre speaking of: longtubes, no cats, cutout and a the biggest(quietest) magnaflow. my truck is very quiet with the cutout closed. this is the first time ive ran a muffler besides a flowmaster and ill never buy anything else again

 

Would a stock muffler be quieter than a the longest magnaflow?

 

I ran a stock muffler on my old truck at first with my cam, and it was very quiet. I couldn't compare it to the big magnaflow's, but hell I didn't have to buy one either! It really performed very well.

 

borla pro-xs,

quiet and it has a good rumble when you get on it...

 

I put two Magnaflow mufflers in series in my Avalanche, and it sounded like an electric truck. Especially with the Radix. Pretty funny.

 

If you run 2 big magnaflows you wont need cutouts unless you just want noise.
